The surface 11 s 1 is spaced apart from the top surface of the substrate 10 by a distance. In some embodiments, the number of the step structures can be changed depending on design specifications. For example, there may be number of N step structures, wherein N is an integer equal to or greater than 1.

The antenna 12 may be disposed on the step structure of the support structure 11. The antenna 12 is disposed on the surface 11 s 1 of the support structure 11. In some embodiments, the antenna 12 includes an antenna pattern 12 a and an opening 12 o. In some embodiments, the antenna 12 can be integrated formed without any openings. In some embodiments, a lateral surface of the antenna 12 is in contact with the surface 11 s 2 of the step structure. In some embodiments, a lateral surface of the antenna 12 may be spaced apart from the surface 11 s 2 of the step structure by a gap (not shown).

Dielectric materials can be used in the manufacturing process of a semiconductor package device. Currently available dielectric materials may have a loss tangent or a dissipation factor (Df) that is greater than about 0.003 and a dielectric constant or a dissipation constant (Dk) that is greater than 3. Air or a vacuum can have a Df of approximately “0.” Air or a vacuum can have a Dk of approximately “1.” Dk and Df values of a dielectric layer may affect the performance of an antenna that is disposed adjacent to the dielectric layer.

Experiments may be conducted on two antennas, one antenna has a surface exposed to air (or a vacuum, with a Dk of approximately 1), and the other antenna has a surface covered by a dielectric material with a Dk of approximately 4. Experiment results show that the antenna having the surface exposed to air (or a vacuum, with a Dk of approximately 1) has a peak gain that is 2.3 times that of the other antenna having a surface covered by the dielectric material with a Dk of approximately 4.

Experiments may be conducted on two antennas, one antenna having a surface covered by a dielectric material with a Dk of approximately 2, and the other antenna having a surface covered by a dielectric material with a Dk of approximately 4. Experimental results show that under the condition that the thicknesses of the dielectric materials covering both antennas are the same, the antenna having a surface covered by the dielectric material with a Dk of approximately 2 has a peak gain that is 1.3 times that of the other antenna having a surface covered by the dielectric material with a Dk of approximately 4.

For example, as shown in FIG. 1A, parts of the antenna 12 can be exposed to air (or a vacuum), and in that case the performance of the antenna 12 can be about 1.3 to about 2.3 times that of antennas that have a surface covered by dielectric materials in accordance with some comparative embodiments of the subject application.

As used herein, spatially relative terms, such as “beneath,” “below,” “lower,” “above,” “upper,” “lower,” “left,” “right” and the like, may be used herein for ease of description to describe one element or feature's relationship to another element(s) or feature(s) as illustrated in the figures. The spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. The apparatus may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein may likewise be interpreted accordingly. It should be understood that when an element is referred to as being “connected to” or “coupled to” another element, it may be directly connected to or coupled to the other element, or intervening elements may be present.

Ranges can be expressed herein as from one endpoint to another endpoint or between two endpoints. All ranges disclosed herein are inclusive of the endpoints, unless specified otherwise.

As used herein, the terms “approximately,” “substantially,” “substantial” and “about” are used to describe and account for small variations. When used in conjunction with an event or circumstance, the terms can refer to instances in which the event or circumstance occurs precisely as well as instances in which the event or circumstance occurs to a close approximation. For example, when used in conjunction with a numerical value, the terms can refer to a range of variation less than or equal to ±10% of that numerical value, such as less than or equal to ±5%, less than or equal to ±4%, less than or equal to ±3%, less than or equal to ±2%, less than or equal to ±1%, less than or equal to ±0.5%, less than or equal to ±0.1%, or less than or equal to ±0.05%. For example, two numerical values can be deemed to be “substantially” or “about” the same if a difference between the values is less than or equal to ±10% of an average of the values, such as less than or equal to ±5%, less than or equal to ±4%, less than or equal to ±3%, less than or equal to ±2%, less than or equal to ±1%, less than or equal to ±0.5%, less than or equal to ±0.1%, or less than or equal to ±0.05%. For example, “substantially” parallel can refer to a range of angular variation relative to 0° that is less than or equal to ±10°, such as less than or equal to ±5°, less than or equal to ±4°, less than or equal to ±3°, less than or equal to ±2°, less than or equal to ±1°, less than or equal to ±0.5°, less than or equal to ±0.1°, or less than or equal to ±0.05°. For example, “substantially” perpendicular can refer to a range of angular variation relative to 90° that is less than or equal to ±10°, such as less than or equal to ±5°, less than or equal to ±4°, less than or equal to ±3°, less than or equal to ±2°, less than or equal to ±1°, less than or equal to ±0.5°, less than or equal to ±0.1°, or less than or equal to ±0.05°.

For example, two surfaces can be deemed to be coplanar or substantially coplanar if a displacement between the two surfaces is equal to or less than 5 μm, equal to or less than 2 μm, equal to or less than 1 μm, or equal to or less than 0.5 μm. A surface can be deemed to be planar or substantially planar if a displacement of the surface relative to a flat plane between any two points on the surface is equal to or less than 5 μm, equal to or less than 2 μm, equal to or less than 1 μm, or equal to or less than 0.5 μm.

As used herein, the terms “conductive,” “electrically conductive” and “electrical conductivity” refer to an ability to transport an electric current. Electrically conductive materials typically indicate those materials that exhibit little or no opposition to the flow of an electric current. One measure of electrical conductivity is Siemens per meter (S/m). Typically, an electrically conductive material is one having a conductivity greater than approximately 10⁴ S/m, such as at least 10⁵ S/m or at least 10⁶ S/m. The electrical conductivity of a material can sometimes vary with temperature. Unless otherwise specified, the electrical conductivity of a material is measured at room temperature.

As used herein, the singular terms “a,” “an,” and “the” may include plural referents unless the context clearly dictates otherwise. In the description of some embodiments, a component provided “on” or “over” another component can encompass cases where the former component is directly on (e.g., in physical contact with) the latter component, as well as cases where one or more intervening components are located between the former component and the latter component.
